To all whom it may concern.

Be it known that I, IRA D. PERRY, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented new and useful In p'rovernents in. Motor-Vehicle Steering(tearing, of which the following is a full, clear, concise, and exactdescript1on,-referhad to the aceompanyingdraw g;

ence being ingfiformmg a part of this specification;

llS invention has relation to that type of motor vehicle steeringmechanism which em}, ploys a planetary gearing between thesteering wheeland the steering post proper, and theobject of my invention is to soconstruct the mechanism that it may be readily ren dered ino )erative,to thereby prevent the stealing o a vehicle, since, unless -the steeringmechanism isoperative, it will be impossible to drive the vehicle underits own power, as more fully hereinafter set forth.

In the drawing annexed-,-

ig. 2 is va transverse section on the line 2-2 of Fig. 1;

-Fig.- 3 is a vertical sectional view illus-i trating a slightmodification; and

--Fig. at is a deta l view illustrating the manner of securing thepinagainst acci- In the drawing, the numeral fidesignates the usualsteering post in the upper end of which an axial bore 6 is formed toreceive the *lower end 7 of the stud shaft 8, which carries the steeringwheel 10, thiswheel'be ing fastened on the reduced upper end "90f theshaft 8 by means of a nut 11.-

andits connected parts be withdrawn upwardly from the housing, thepinion 19' passing up through the bore in the cap, thereby making itpossible by simply removing these parts to render the steering imechanism entirely inoperative.

To hold he stud in olperative position. To iasten the parts. is'position, a pin 23' is inserted in the 20, this pin being readilyremovable by sunply sliding it out of the hole.

In a steerii-ig mechanism for vehicles, a steering posha housing at theupper end thereof provided with a closure cap, a stud shaft entering thehousing tllLUi-lgh a hore in the cap and carrying at its upper outerend. a steering wheel and at its lower inner en a pinion a planetarygearing within the housing of which said-pinion forms a part, saiclqstudshaft with its pinion and steering wheei being capable of an upward orendwise movement to thereby enable the pinionito be disengaged from thereliiaind'er of the, gearing, and a device--in-addition to the housingcap for ino'vably holding the stud shaft and pinion in operativeposition, said pinion. having a diameter less than that of the bore ofthe cap to enabie the pinion to be lifted. up through the bore, the studshaft being smaller in diameter than said here and being provided with abushing iitting the bore and the shaft and adapted to be removed withthe shaft.
